Question 648887
Assume that the readings on the thermometers are normally distributed with the mean of 0(degrees) and a standard deviation of 1(degrees). A thermometer is randomly selected and tested. Find the probability that the reading in degree is... 
Greater than 1.33?
-------
z(1.33) = (1.33-0)/1 = 1.33
----
P(x > 1.33) = P(z > 1.33) = 0.0918
